As one of the other posters indicated, you have to do Neah Bay and do the short hike to Cape Flattery. It's the most northwestern point in the 48 states. We stayed at the Hobuck Beach Resort with our 32' Class A. There are plenty of spots open as Neah Bay is pretty remote and off the beaten trail. But, don't expect resort level accomodations. Most of the people that were near us were long term residents (mainly fisherman). Nonetheless, it's right on the beach and we truly enjoyed the area.
On the western side of OP, I would recommend a couple places to stay, Kalaloch and Quinalt Rain Forest. Kalaloch is right on the Pacific Ocean and is popular and most spots don't have sewer. Quinalt RF is private run and has hookups but no sewer. Both of these have a ton of hiking trail heads nearby.
On the northern side of OP, Sol Duc RV Resort is nice as you can use the hotel accommodations when staying in the RV spots. THe hike to Sol Duc hot springs is easy and a must.
Before you leave the peninsula, there is a state campground called Fort Worden in Port Townsend. We stay here every Memorial Day weekend.
We've all been there. Just take a pause and organize the problems in a list. As many have already stated, just knock them out one at a time. A few days back in the normal daily grind will bring the RV bug back.
If you can go as far as Bothell (up I405 about 15 minutes) then I would suggest Lake Pleasant RV resort.
x2 There is a RV park right on I 90 in Bellevue called Trailers Inn but wouldn't recommend it if you are looking for grass or a pool. It's basically a parking lot.
I live in a HOA which has stricter guidelines than the city. I have to store my RV offsite and only allowed 24 hours in front of my house and allow 5 feet clearance of any mailbox. City rules are 72 hours.
